9 Power Supply Recommendations
The input of the LP3470 is designed to handle up to the supply voltage absolute maximum rating of 6 V. If the
input supply is susceptible to any large transients above the maximum rating, then take extra precautions. An
input capacitor is optional but not required to help avoid false reset output triggers due to noise.
10 Layout
10.1 Layout Guidelines
• Place components as close as possible to the IC
• Keep traces short between the IC and the C₁ capacitor to ensure the timing delay is as accurate as possible.
